Get URL parameters and transcode them through jquery_jquery

jquery obtains URL parameters and transcodes them. First, it constructs a regular expression object containing the target parameters, matches the target parameters and returns the parameter value

The code is as follows:

<script type="text/javascript"> 
$(document).ready(function(){ 
var pic_url=getUrlParam("picture"); 

$("#childpic").attr("src",pic_url); 
var content=getUrlParam("content"); 
$("#content").html("<b>"+content+"</b>"); 
}); 
function getUrlParam(name){ 
//构造一个含有目标参数的正则表达式对象 
var reg = new RegExp("(^|&)"+ name +"=([^&]*)(&|$)"); 
//匹配目标参数 
var r = window.location.search.substr(1).match(reg); 
//alert(r); 
//返回参数值 
if (r!=null) return decodeURI(r[2]); 
return null; 
} 
</script>

Test url: http://xxxx.html?picture="XXXX"&content="Hello!"
